2 Pack Lithium 3.0Ah PC18B Batteries Replacement for Porter Cable 18V Battery PC18BL PC18BLX PCC489N PC18B-2 Compatible with Porter Cable 18V Power Tools

I bought two of these for my Black and Decker 20V tools. These batteries fit the existing chargers fine physically and seem to charge correctly with them. I can't really compare these batteries to the original because I purchased the 4000mAh high capacity batteries to replace the standard batteries. They are thicker batteries and they last much longer than the original (which they should as they are larger). These larger batteries fit all my tools without modification except my blower. The plastic on the handle kept the larger battery from seating all the way in the blower. I took my Dremel and ground down a bit of the plastic and now the battery fits my blower also. Could not be happier with these!

The Upgraded 3000mAh battery appears to be just what I wanted. Although I haven't had it long, I can already tell it is extending the run time on my Black & Decker Weed Eater and blower. With the standard battery that comes with the units, I could do the trimming and blow off the driveway and mower, but that was all the power it had. With the new battery pack I have trimmed and blown twice and have yet to recharge. Not sure on the longevity. Time will tell.

Has performed as expected. I mow lawns and bought this because I needed the extra battery life to trim the lawns I mow and gives me about a full hour of battery life which is much better than the smaller black and Decker batteries that give me about 20-30 minutes. Although charging a fully dead one will take pretty much all day so make sure it's charged the day before you use this battery. But I've used this battery about 3 weeks now and it's still going strong.

Time will tell on durability/longevity. Fits tools fine and seems to have good power. Will update after extended use. Fraction of the cost of OEM batteries so we'll see how it lasts.

As quickly as the little blower drains its battery I wanted to at least have a spare. YES. After charging I attached this to the B&D blower. The power was immediately noticeable. I not only have a longer lasting battery back,but you can actually see / feel the difference in power from the B&D standard battery!

I am glad I bought this pack. It makes the blower more useful due to the longer running time with the larger battery. The blower power also seems more than the OEM battery it came with.

Fast delivery of an excellent product. This really makes my weed whacker go longer than I need it...making it all worthwhile

I haven't had it that long. It seems to a quality product. Time will tell. Prompt seller.
